主なメリットと利点
Seamless Low Flow Integration: The standout feature of the EJA115E is its Integral Flow Orifice. By mounting the orifice directly to the transmitter body, the system captures minute pressure drops across very small bore pipes (typically 0.5 to 1.5 inches) that traditional remote orifice plates might miss.
Elite Square Root Accuracy: Optimized for flow calculations, the EJA115E delivers a 0.055% square root output accuracy. This ensures that the conversion from differential pressure to flow rate remains precise even as the flow nears the lower limits of the sensor’s range.
Market-Leading 10-Year Stability: To minimize maintenance and life-cycle costs, the EJA115E offers a stability rating of ± 0.1% per 10 years for the differential pressure sensing element. This long-term reliability ensures that flow measurements stay consistent without the need for frequent zero-checks or recalibration.
Certified for Safety Loops: Reliability is guaranteed by Exida and TUV SIL 2/3 certification. The EJA115E is designed to provide dependable flow data within Safety Instrumented Systems (SIS), protecting critical processes from low-flow or no-flow conditions that could lead to equipment damage.
Versatile Communication Options: To fit into any plant architecture, the EJA115E supports a wide array of protocols, including HART 5/7, FOUNDATION Fieldbus, PROFIBUS PA, and BRAIN. A 1 to 5 VDC HART 7 Low Power option is also available for remote sites powered by solar or battery.
Fast Response for Dynamic Control: With a response time ranging from 90 ms to 150 ms, the EJA115E provides the rapid feedback required for high-speed dosing pumps and fast-acting control valves, ensuring stable flow regulation in volatile processes.
